Best Known (106, 106+133, s)-Nets in Base 4

(106, 106+133, 130)-Net over F₄ — Constructive and digital

Digital (106, 239, 130)-net over F₄, using

t-expansion [i] based on digital (105, 239, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(106, 106+133, 144)-Net over F₄ — Digital

Digital (106, 239, 144)-net over F₄, using

t-expansion [i] based on digital (91, 239, 144)-net over F₄, using
- net from sequence [i] based on digital (91, 143)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 91 and N(F) ≥ 144, using
    - Drinfeld modules of rank 1 [i]

(106, 106+133, 1202)-Net in Base 4 — Upper bound on s

There is no (106, 239, 1203)-net in base 4, because

1 times m-reduction [i] would yield (106, 238, 1203)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 200232 549275 175462 700865 085773 288950 159860 709565 494054 414918 732519 996077 413810 328634 956904 374242 444191 682517 142733 660025 250295 770428 058404 282250 > 4²³⁸ [i]
